COOKING APPARATUS.

Specification of Letters Patent.

Patented Sept. 2, 1919.

Application filed August 21, 1916. Serial No. 116,092.

1 '0 all whom it may concern:

Be it known that 1, JOHN S. BAKER, a citizen of the the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Cooking Apparatus; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention is a novel improvement in cooking machines of the type shown in my Patent #1,182,832 of May'9, 1916; and the object of the present invention is to enable cans to be discharged from any desired run of the canway and at the same time to always maintain a substantially uniform control or closure of the discharge; to do away with a multiplicity of adjustable devices for varying the discharge of cans; to simplify and cheapen the construction of the machine, and to provide a construction which can if desired be readily adapted for use in cooking goods requiring high temperatures.

The invention also provides means for maintaining any desired uniform depth of water in. the cooker; also novel means to insure the dropping of the cans from the carry-oil devices; and to provide novel means for shifting the dis-char e openings of the canway. The invention a so provides other novel detail improvements hereinafter mentioned; but the principal feature of the present invention is a novel slidable means for varying the point of discharge of the goods; this and the other novel features of the invention will be clearly understood from the following description in connection with the accompanying drawings which illustrate one practical embodiment of the invention and will enable those skilled in theart to adopt and use the same. In said drawings:

Figure 1 is a sectional side elevation of a cooking machine of the general type shown in my aforesaid patent.

Fig. 2 isv a front end view of such machine.

Fig. 3 is an enlarged sectional view of one end of said machine.

Fig. 4 is an enlarged detail front view showing the adjustable discharge slide.

Fig. 5 is an enlarged detail view of the carry-off devices.

Fig. 6 is a detail section on line 6-6 Fig. 4.

Referring to said drawings, 1 designates a tank which may be of any suitable construction, and is shown as provided with an internal spiral canway 1, constructed sub stantially as described in my aforesaid patent. The cans may be fed onto this canway 1 through a feed chute or chutes 2, and the cans entering the cooker through the right hand chute 2 will pass into the first run of the spiral canway.

The cans ma be fed and discharged at the same end 0 the cooker; or at both ends if desired. The end wall of the cooker may be formed of a metal plate 4 to which the feed chute 2" is attached. This metal plate plate 4 hasan' enlarged opening 4 in it extending substantially across all the runs of the canway or the entire width of the series of canways.

On the lower edge of this opening is a groove 4 in which is supported the lower edge of a transversely movable sliding plate 5, the upper edge of which is confined in the upper edge of the opening and guided in a groove formed between the upper outer edge of the plate and a bracket or casting 6 rigidly attached to the plae 4 above the upper edge of the opening. The slide 5 can be slid back and forth transversely of the cooker and beneath the feed opening, being retained and guided in position as described.

The slide 5 may be made longer than the width of the tank, according to the number of runs in the canways, or the number of different points at which it may be desired to discharge cans. The slide is provided with an opening 5 through which the cans pass out into a receiving trough 7 hereinafter referred to.

The casting 6 not only forms a guide and retainer for the upper edge of the slide 5, but is also provided on its front edge with a rack 6 beside the upper edge of the slide 5 which rack is en aged by a pinion 5 attached to a hand w eel 5 mounted on a stud attached to slide 5. As the rack 6 is plurality of series of cans through the machine at the same time and give each series any desired length of cook, or the same or difi'erent lengths of cook as desired.

An essentially novel feature of this invention is having the discharge controlled by a slide having a single opening, such slide being adjustable so as to bring this opening into register with any desired run of the canway. Another feature of the invention is novel means for taking off the steam in case high temperatures are desired in the cooker. By means of the pipe 9 the water in the cooker can be maintained at the proper level at all times. The device for dischar 'ng cans from the trough into the chute is also very useful and is particularly efiicient. The device 7 operates to straighten out the cans and cause them to enter the chute 7* properly just at the moment they roll ofl of the carrier 7.

As shown in Fig. 1 instead of having the discharging device duplicated at each end of the machine the cans may be guided around the rear bends of the canway by an adjustable curved plate 10 hinged or adjustably attached at its bottom in any suitable way to the bottom plate of the canway, as indicated at 10*. This plate is adjustable so that the space between its inner face and the curved portions of the bars can be varied to suit cans of different size and properly direct them around the bends, by swinging or adjusting the plate inward or outward. As shown the upper end of the plate can be adjusted by means of bars 11 pivotally connected to the plate at their inner ends, and projecting outwardly through openings in the wall of the tank and provided with notches 11 which can be engaged with the end wall of the tank to hold the plate in the desired adjusted position. The plate may also be further supported and adjusted if desired by any adjusting screw or screws 12 extending through the end wall of the tank and engaging the central portion of the plate as shown.

While I have referred in this description to the use of cans I have done so simply as illustrative and-not as limiting the invention, for the apparatus can be used for treating packaged goods of any desired kind, although the invention is particularly designed for use in cooking canned goods or goods in cylindric packages which can be rolled along the ways.

I claim:

1. In a cooking apparatus the combination of a chamber, a spiral canway therein, a member having an outlet, and means for adjusting the member to cause the outlet to conform with any run of the canway from which it is desired to discharge cans.

2. In a can cooking a paratus the combination of a casing provi ing ecooking cham- 4. In combination, a cooking chamber having a feed opening, and a plurality of discharge points, a member for covering said discharge points and provided with an out let opening, and means for positioning said member to bring its outlet opening in register with any of said discharge points.

5. In combination a cooking chamber, a spiral canway therein, means for moving cans along said canway, an opening adjacent one end of the canway and extending past a plurality of runs thereof, a slide closing said opening and having an outlet opening, and means for adjusting said slide to bring said outlet opening into register with any desired run of the canway.

6. In a cooker the combination of a Cllilll'l her, a feed chute extending into the chamber, a series of pusher bars for moving cans in the chamber, and guards adjacent the inlet end of the feed chute adapted to prevent the pusher bars catching on the feed chute.
